8was dividedby some numberthen added to13.next this difference was multiplied by 2 which gave a product of 30 find the answer

y=x³+2 or f⁻¹(x)=x³+2

Step-by-step explanation:

To find the inverse of the radical function, we replace y with x and x with y. Then, you solve for y.

                       [replace y with x and x with y]

                       [cube both sides to cancel out the cubed root]

                         [add both sides by 2]              

Now that we have switched the variables and solved for y, we know that the inverse function is y=x³+2 or f⁻¹(x)=x³+2.
